aren't we americans basically "slaves" to the natural resource rich countries (especially oil)?  and won't we eventually run out of things to offer to trade for that oil, which will result in a degradation of our standards of living, and ultimately freedoms?  then what?  do we continue to build our military so we can trade its services, or invade countries with resources we need?  And/or do we invest heavily in nuclear energy, the seemingly only viable option for continuous energy to someday be able to stand alone, without having to sell the ground from under our feet to keep our standards of living?
